I paid a total of $25 plus tax and got a free data plan along with some free voice and text. The voice has some echo, so I am only using the data plan as my gps in the car. The service is from freedompop. If you have your own Sprint cell phone, you may pay $20 to use the “Bring Your Own Device” program, a little cheaper than what I paid (I don’t have a unused Sprint cell phone lying around). Even though freedompop does not promote their free data plan service as much, I will show you how to downgrade your plan to get the free service.

I will also show you my cheap and simple way to attach the cell phone in the car. Thought it does not look glamorous, this is one of the most practical and useful life hacks.

One more note: the free data plan is not an unlimited data plan, so you still need to watch your quota. Also you are getting something free or cheap, so don’t expect the best support.

Most times the engine oil filter is not too hard to remove, but occasionally you may encounter a very difficult one. When that happens, if you can’t locate your best special oil filter wrench or you don’t have another driveable car to run to the store, this video should help you. It would be nice if you can make use of the tools you already have in your garage. Depending on what items you have and the kind of car you have, I will show you 4 different ways to remove a stuck engine oil filter. Again it should not cost you much. Note that your garage may have somewhat different items, in which case my video will inspire you to find your own solutions.

Note that tools for oil changing are not that expensive. However, if you can’t locate them or if you don’t DIY often, simple tools shown in this video could come in handy. If you do change your own engine oil often, then investing in better tools may not be a bad idea.
